ID (Autonumber) increments by 1 even when New Data Form NOT saved

Hi Forum,   I want to only increment my ID number when the reservation is saved. Not increment when I haven't save the page. Am I doing it correct?   Here is my microflow and domain module   this is the microflow i use to book the reservation

Hi Wenyu Huang,

 

Yes this is correct. Autonumber will always increment +1 on create of an object, even if it is not committed after that.

 

If you want to control the number you should revert to building your own numbering mechanism using microflows.

Hello Wenyu,

 

It can work like that, but some considerations that you need to make.

 

Why does the reservation number only needs to add up up after save ?

Is it possible to cancel a reservation after it is saved ? What to do in this scenario if yes ?

What is the benefit of a unique ID and a Reservation ID ? 

 

So yes it can work like this but my honest opinion is to just use the autonumber you already had and take for granted the jumps in the ids because this is a more robust process.

 

Hope this helps,

 

Good luck!

Thank you for your support!

 

I rethink about it and now I add ONE MORE entity in demain model,

which is UniqueID,

 

And I add TempID to be the attribute of Reservation.

I want to use a microflow to let Unique ID mapping with TempID when I click save.

How can I map them_?

 

I don't know what to key in here

Yes, you will have to create your own numbering mechanism.
